Now that the Dev-Team has release the PwnageTool 3.1.5 to jailbreak iPhone 3.1.3 firmware on Mac OS X. So, it’s time to write a guide on how to jailbreak iPhone 3.1.3 using PwnageTool 3.1.5. PwnageTool along with jailbreaking, also preserves iPhone Baseband so that so may unlock it later.

This guide is for Mac users only because PwnageTool is available for Mac only. Windows users can either use RedSn0w or Sn0wbreeze or wait for the upcoming ready made custom firmwares only at iPhoneheat.com.

Disclaimer:This guide is for testing and educational purposes only. Use it at your own risk, we cannot be held responsible if anything goes wrong.

ok… Let’s start jailbreaking iPhone 3.1.3 using PwnageTool.

Jailbreak iPhone 3.1.3 Firmware

Update your iTunes to latest version and Backup your iPhone.

Create a folder on your desktop and name it: Pwnage. Then download the files linked at the bottom and put into Pwnage folder.

(Download through Firefox because Safari often auto extracts ipsw file)

Step 1
Double click PwnageTool_3.1.5 dmg file to mount it.

Click and drag the PwnageTool icon to Pwnage Folder you created and then open it from there.

Warning Box will Popup. Just hit the OK button.

Step 2
Make sure you select Expert Mode from Top menu

Step 3
Select your device. A big Green check mark will appear on the selected device.
Now hit the big Blue Arrow button at bottom right to proceed.

Step 4
On the next page, PwnageTool will automatically find the IPSW file. If not found then click “Browse for IPSW” button and select the downloaded IPSW OS 3.1.3 file from the Pwnage folder. A check mark will appear next to it.

Then hit Blue Arrow Button to proceed.

Step 5
On the next page you will have 6 choices. Select the General and hit Blue Arrow Button to proceed.

Step 6
This is the most important step. Please read carefully about selecting activate the phone option. You will know you didn’t choose the right option if you don’t have signal after jailbreaking.

On the next Page you can decide your Root Partition Size where OS resides. Click activate the phone (only if you’re on unofficial carrier).

***Deselect Activate the phone option if you are on official carrier. For the 3.1.3 firmware you may have to increase the size of your root partition slightly for the IPSW build to be successful. I like 1GB.***

The Bootneuter settings are greyed out for the iPhone 3GS and 3G and iPod Touches. Click the blue arrow button.

The next screen will show the Cydia settings menu. It allows you to create custom packages so you do not have to manually install them later.

Go to Download packages tab.and hit the Refresh button to display all the available packages. Double click your desired package, it will be downloaded and will be available under the Select Packages tab.

When you have downloaded your desired packages, go back to Select Packages tab and check mark the ones you want.

then hit the Blue Arrow Button to proceed.

Custom Packages Settings will displays listed package settings for your custom IPSW. Leave these settings as is for now. Just click the Blue Arrow Button to proceed.

On the next Custom Logos Settings menu, you’ll be able to add your own images as boot logos. Click the Browse button to select your Boot logo and Recovery logo. I just use defaults so deselected all options.

Click the blue arrow button to continue.

Step 7
Now you are ready to build your custom firmware. Click the build button to select it, then click the blue arrow button to proceed.

Step 8
You will be asked to Save your custom .ipsw file. Save it to the same Pwnage folder.

Step 10
When prompted if your iPhone has been Pwned before, Click No. It allows for a more thorough restore.

Step 11
You will be asked to turn OFF the device. Make sure it is connected to the USB port.

Step 12
NOTE: If you’re already jailbroken (by whatever means), you don’t need to mess around with DFU mode at all. Just create (or get from a friend) your custom IPSW and Option-Restore (Shift-Restore on Windows) to it via iTunes. Don’t enter DFU mode at all. Please make sure you are restoring to the custom IPSW, not the stock one from Apple! For best results, use the latest iTunes (9.0.1) — which includes a nice new application organizer.

If it’s the first time you’re jailbreaking your iPhone, Be ready to follow directions now to get into DFU Mode.

You will be asked to hold the home button and the power button for 10 seconds.

Then, you will have to release the power button and hold the home button for 10 seconds to enter DFU.

If you failed to follow the instruction, it will show you a message asking if you want to retry?. Click Yes.

Unplug the iPhone from the USB. Turn it OFF, then turn it back ON. Reconnect it to USB and turn OFF the iPhone when prompted.

When followed correctly, PwnageTool will display a message telling your that it successfully entered DFU mode. iTunes will also pop-up.

Step 13
In iTunes, hold the Alt/Option key and hit Restore.

Step 14
from the popup window, browse to the Pwnage Folder and select you custom .ipsw file that you just created and click Open Button.

Step 15
iTunes will now restore the firmware on your iPhone. This can also take up to 10 minutes.

When done. You have successfully Jailbreak iPhone 3.1.3 firmware.

Unlock iPhone 3GS, 3G 3.1.3 firmware

Now in Order to Unlock iPhone 3GS or 3G 3.1.3 firmware follow this old Guide which also works for OS 3.1.3 if you jailbreak iPhone using PwnageTool:

If you don’t want to go through all the steps, we suggest iPhone 3G( if don’t care about unlock), 2G,iPod Touch 1G and 2G (old boorrom) to use RedSn0w to jailbreak their devices. Guides are linked below:

then do you know any way for downgrading my iphone, 3.1.3, 3gs. i find out that i cannot do it with suarki’s server because my “SHSH” files are not saved in suarki’s server.
do you know how to create an server for sign the downgrade the .ipsw file.

If I jailbreak the 3.1.2 new bootrom 3GS, as far as I know, when the phone goes off, I have to use BlackRa1n to boot it up.

If I first jailbreak it in a Mac, so I can boot it up in Mac with Blackra1n, how about when I am at now at another place, there is a Windows computer, can I also boot it up with Windows version blackra1n?

hi guys accidentally updated my iphone and now its from the start, fabric settings. i just tried this and it didnt work. i did all the steps that i was supposed to do but when i come to the restoring part it says error and fails. its says something with …(1600)..something. can someone help me please? can someone put up his/hers working ipsw on some sites like rapidshare or something? please guys help!

I have tried to JB my iphone, None of the IPSW files i have downloaded work. I have a 3G I phone. Right now i am no jailbroken. I have ATT service so i don’t need it unlocked. Can someone please point me in the right direction to find the proper IPSW file.

I am new with the I-Phone just got 1 the 3gs i want to jailbreak it and unlock it but at the start of the post it is written that this works only with the old bootrom of the 3gs does it mean that anybody having the new bootrom cannot jailbrak it as of now till the new crack comes out???? and how can we determine if the bootrom is new or old please help i travel a lot and use diff carrier’s at diff places.

I accidentally updated my 3g iphone thru itunes to 3.1.3.. Its baseband now is 5.12.1, please help me out or guide me the instruction. I beieve i can follow it cuz I’ve been around iphone for too long too. I am just a user not a developer like u guy…

I accidentally updated my iPhone 3GS to OS 3.1.3.
Serial is xxx28 (I believe that this should be old BootROM).
I don’t have SHSH in Cidya server but these steps seems never required about SHSH. (right?)

I had followed the steps int this post, but I couldn’t get expected result.
The iTunes returns the error 1600 or 1604.
And it would roop from the end of step 12 to step 14.

Hello guys,
After reading for a couple of hours on this site i still have a question and i hope you can clear it out for me. I have an Iphone 3G 05.12.01 baseband MB500B model. I understand it can be jailbroken but should i chose to do it with the pwnage tool or with the redsnow? I do not care about the unlock since i have been using same mobile network since 2000. I also have acces to both, pc and mac. Thank you in advance

I have been in the process of jailbreaking my iPhone since last night using PwnageTool. Finished with jailbreak. Successful, but no cell reception. I’ve been with AT&T since second Gen, so didn’t think I needed to unlock. Now what…??

Great morning, I want to say thanks for an great blog about a subject I have had an curiosity in for quite some time now. I have been exploring in and reading the responses and only wanted to express my many thanks for giving me some really interesting reading material. I anticipate reading more, and taking a more active part in the talks here, while picking up some expertise too!

THEN my screen flicks to the USB + iTunes logos and doesn’t do anything from there. If I wait long enough it then puts a error window up. I force quit iTunes then have to use blackra1n to get my phone to boot up.

How do I get round this, so I can restore? I have to use 3.1.3 because apple have stopped signing. Haven’t got alot of choice and I have to restore as my phone is doing some weird stuff.
